I failed all my science courses, I don’t understand much about science but why doesn’t the water just… move like when you jump in normally?

Compare walking into a pool to a belly flop. Or, jumping in from the side vs. the belly flop off a high diving board. The water moves the same, but you hit it harder the further up you are, and the more it resists just because of how fast you are trying to enter it. So, from the side, a belly flop is ok, but from the diving board, it smacks you and leaves a welt. That smack is harder the higher you are when you hit it.
There are techniques to survive, and there are stunt divers that do things to dive from very high heights, like dropping something first to get the water moving before they hit, or bubble water in it. But that does the same thing, get the water moving so it’s easier to move out of the way of your body when you hit.
